Tools are available free for download. Users can turn data layers on and off, zoom in and out, and print the maps. As the "Digital Map - Beta" evolves, the USGS will add historical versions of the topographic maps and will incorporate other data layers including hydrography and contours. Use of the term "Beta" signifies that these maps are initial versions that do not yet contain the full content of the traditional USGS topographic quadrangle maps.
